Arc Flash Minute: Arc Rated T-Shirt Best Practices


What are the Best Practices for Arc-Rated PPE in your Electrical Safety Program?

e-Hazard recommends using AR t-shirts as an undergarment for these reasons:

  1. Adds extra protection by adding that extra layer underneath an AR shirt
  2. Eliminates risk of ignition by taking out ignitable t-shirt (a risk with an ejected arc, arc-in-a-box, or tracking arc in high voltage)
  3. Under sleeves, this makes the upper torso about as great as the protection for the hands and arms.

Manufacturers have tried to make the job of managing your arc-rated undergarment program easier by marking the t-shirts so that they are easier to recognize.

  • Logos on the front of the shirt
  • Different colored collar


This is one of the many concepts taught in our 7 Electrical Safety Habits Training Video.
